application filed February 25, 1908. serial No. 417,164.

.l '0 all whom it may concern:

Be it known that I, FnnDenIoK A. Lioow- SKY, a citizen of the United States, and a resident of the city of Cincinnati, in the county of Hamilton and State of Ohio, have invented a certain new and useful Medical Electrical Device for Medical and Therepeutioal Purposes, of which the following is a specification.

One object of my invention is the eflicient and rapid and economical eneretion of ozone, by novel and economics means.

Another object of my invention is the generation of ozone at stated and desired intervals.

Other objects of my invention will be hereinafter a iparent.

The severe features of my invention and the various functions of the same when used conjointly or otherwise will be a parent from the following desbription and c aims.

In the accmnpanying drawings making a not of this specification, and in which simiin! letters of referei'ice indicate correspond- 25 ing parts, ---Figure 1 indicates a plan view of the apparatus, it being understood that those portionsci the, upper floor which are not occupied with. mechanism are removed, and thereby certain parts of the mechanism below the floor are presented for examination. Fig.2shows lan viewsof the batteries of the ozonizer, am the movable receptacles which contain said batteries, and thepreferred means for enabling the electric currents of said batteries to be with other portions of the mec anism. Fig. 3 is a side plan and elevation showing a diagrammatic view of clockwork, and certain electrical portions of the apparatus in connection with. the clockwork, and also a device for controlling the said clock in timing the electrical exposures or connections for the generation of ozone at stated intervals; also the device for controlling the starting and the stopping of the clock in the said ozonizer. Fig. 4 is a top view of the ozonizer, and which shows the position of the timing screw, the stopping and starting lever, and the electrical switch device aforementioned to control the starting and the stopping of the clock. Fig. 5 is an enlarged view of the wheel and contact s ring and regulating screw shown on n smal scale in Figv Fig. O is a perspective view of the ut in circuit induction coil when suspended and illustratin onemode of suspending the bandage.

I wil now roceed to describe my invention in detai The entire mechanism is supported and held by a suitable framework, and a. useful and convenient kind of such framework consists of a box A, and this box is also preferably provided with a cover A hinged at A, A to the box A. This cover A when brought down covers those portions of the mechanism located on and above the top of the box A.

Batteries B of proper strength are presant, and when my apparatus is portable, the box A is adapted to carry such batteries. And in the illustrated construction, each end portion of the box is rovided with a recess or pocket 1. One of t iese ockets P receives one set of batteries, and tie other of. these ockets P receives the other set of batteries. 'nasmuch as the batteries B will require to be renewed at intervals, I locate one set of these batteries in a drawer C, which is received into one of the pockets 1, and another set of these batteries in a similar drawer C, which is received into the other of these ockets P. A knob C on the end of each rawer enables the letter to be more readily withdrawn from its ipocket P for the inspection of the batteries, or their renewal or replacement, and for the repair of'their immediate electrical connecting ortions.

Where I use batteries of more 1; an one cell, as I usually do, these batteries are electrically connected, and in the illustrative drawingl have shown thebatteries connected in series. Thus the carbon B of one battery is connected to the zinc B of the next, by awire B. Provision is made for electrically connectin these batteries with the circuit wires. Thus t e wire B from the carbon B of the last battery at one end of a series, connects with a metal spring. or springs D elastically standing out from the side or sidesC, of the om the slde or drawer, and the wire l3 from the zinc B of- .i pring or springs tact with thd contact E, and an elastic spring D makes contact with the contact E. On:- advnntage of hnvingthc elastic springs I and D on one side C of the drawer and a similar set of elastic springs D and D on the other side of the drawer is that it matters not whether the drawer is ut into the machine at the right or the left rand of the central ortion, because with the provision of doub e contacts noted, its batteries will always make respectively electrical connections with the respective contacts E and E. Therefore either drawer C can he put in either pocket 1. Another advantage of the presence of such spring contacts D and D on 0th sides 0, C, of the drawer is that those of said sprin s which are on that side of the drawer whic 1 is away from the contacts E and E will ress against that side of the pocket P ad acent to them, and will ress the drawer over toward the. contacts .4 and E and will the better make certain that the spring; metal contacts'D and D on the side of t c rawcr next to the contacts E and E shall respectively make contact with the same.

In the machine is a clockwork F which consists of a series of wheels, 3. spring which can be wound up, means for winding the spring, an escapemcnt, and the like, in other words this clockwork has the usual arts adapted to enable the clock to tick ofl' ill? customary seconds of time. Inasmuch as the construction of such clockwork F is well known, and is in common use in time keepers, the clockwork is shown conventionally and not in detai A device for starting and stopping the clock is shown and consists of a lever G fulcrumed at G to a stationery part of the frame, and havin a handle arm ('i and a. hooked arm G, adapted when the handle (l is moved toward the right, see Fi s. 3 and 5,

to engafe the periphery of adiskl fixed ounrotatah e 'ivot o the clockw'rn'k; and'stop this disk I- from further rotation, and thor by stop the motion of the clockwork 'When this handle arm G is moved toward'tho left, the hooked arm G is thrown out of engagement with this disk H, and the latter and lheclockwork impelled by the wound-up spring is free to go on moving, and to operate the device for directly generating ozone. Proferably a slotted guide G, stationary in the frame, is present, and in the slot of this guide. the up or iart of the handle arm (l of this lover (1 is located. The handle arm is free. to move to the right or left as before indicated but cannot move laterally and thus go out o its correct lino of movement.

Located on o stationarypartol the machine is the metal stud J, and this carries a swing arm K. whose free end K extends over to the disk ll. (hi-this dish ii are one or more studs or posts ll, ll. 'lhcsc posts are preferably of a. trian ular shape for the hottcr performance of Eli functions for which they are designed. The electrical current passes through the stud J and the spring devices directly included in the genera! ion of the ozone. But. when by the revolution of the disk H, the stud is out of contact with the spring arm K, then the current of electricity is broken and no longer acts in the work of generating ozone.

The electric wires of the circuit are provided with a switch wherein the electric current may be imported to the marhinc or cut oil therefrom at will in the present illustrative instance, 1 have located the switch L as shown. This switch L is ivoted at one. contact If and is adopted when swung to have its other (fine) end moved over and into contact with the Contact L When thus "moved, the electrical circuit is established in the machine. The, switch comm-tli is connected to the one pole of the batteries, and the switch contact L is connected to the other pole of the batteries, it being understood that the electric circuit with contact L docs pass from the-batter; through the clockwork, vim: disk l-I, stud I1, and spring arm K, and stud J, subject to the interru 'itions at the disk II and stud ll as aforementioned, before reaching the said switch contact if. But the switch I! might be pivoted at contact I, and more over onto and oil from contact L and be equally eil'crtive.

An induction coil X ispresent, and it is preferably inclosed in a suitable sup orting recoptaclo,hcre illustrated use. box M This induction coil is employed to multiply said battery current to a very high electromolivo force. This battery current is carried from the-induction coil by secondary or high ten sion wires M, M, to their respective tormirials M, M. From each terminal M, a coin ductor Til preferably in the shape of a rod, with :1 flat metallic terminal plate M", conducts this high tension current to an adjacent glass plate N. There are two of such glass plates at a requisite disiunrc the one from the other. ()no terminal conductor M, M is in contact with the nearest side of one glass plate N while the other terminal conductor M, M is in contact with that side of the other glass plate N which i.-= nearest to it. Thus this high tension current comes in contact with these glass plates N. and

tends to highly elcctril'y the said glass plates. This current produces a fluorescence across the gap or air sparc id between the. said During this time viz; while the current is passin from one, of these glass lateszN to the other of those glass plates 1 the itir is not only proscnt in said space,'but owing to 5 anincreasc oftemporcture, it moves through said space M". The air is there concern minted and after passing through the said spies M between the said glass plates N, N, becomes ozonizcd.

Whenever the switch L, L, L completes tho circuit, the current passes from the spring contact. E of one-battery receptacle, on 'th rjou li the circuit wire to the clock and to the disx H, and the current fromthcbetl5 tor-y in the other battery receptacle, passes.

through contact E and wire it and through the said switch and the wire R to the said spring contact K, F. At the some time, the current from the first nunied receptacle is established between i the contcct E and through the linoSto the induction coil X, nlnd tho current is estnblishcd from the contact E oft-ho sccond butter (in the second receptacle) by the line T to the. induction coil X, Thus the: cut-ire circuitbetwocn the hottorics and the. said induction coil and thedisklll on the one hand, and tho spring contact on the other hand is coi'oplotsd, but

the current is not continuous and in action, eirocpt when nsth'e disk l-l I'ovolvos one of the posts H thercon comes into contact with the spring contact K, K. Whcn one of these posts. H, as the disk H rcvolvesby the clocltwork, reaches the spring contact K, the entire circuit is established and the cloctn'cal current posses across the air space M from the glcssplstc to the opposite glass plate N, and generates ozone. This ozone is steadily manufactured until by the. onward 4o rotatory movement. of the disk H, that-post 1-1? which in cont-sot with tho spring con.- tocll3; has left this spring 1i. 'lhcn the. current is broken until the. ncxt post H" reachcs tbis spring contact K, and thou the clelrtricsl circuit is again established and tho ozone wili be generated until this second post ll pnssos out of contact with tho spring contact Ii. This generation of ozone at. stated intervals is continued so long as do- 59 sired. 'lhcn tho snitch L is mm'od and the electrical circuit is broken.

The length of time the currc'nt is in action and ozonc generated is detsrminod by the length of limo such post H is in couti 1. with the Contact spring ii. In my machine, I have made this length ol' time chnngeubls by a suitable device of which tho following is a.

referred torn I provide- :i. flange V which i islseourcd to the frainc. This flmig has on i 50 opening that is screw threudod. A vertical rod screw tilroudcd, extends through this opening in t'lck bingo V and its screw threud i engages the screw thread of the sold opening. Thus by rotating this rodV in one direction, it is screwed upward, and by rotating it in i tion of the machine.

minesthedin inished len th of electrical ac- W ion the spring contact Kisfrco to move and is not depressed bv the rod V it stays longest in contact with the adjncont moving post H. When the spring contact K is pushed down by the rod it is not reached as soon by the post H" and will not remain as long; in contact with the post H as when it is from contactwith the vertical rod V lhc further the 3 ring contact K decreased by the rod V, tnc shorter in the .lcngt i ottimc in which the post H is in contact with the. spring contact K, and the shorter isthc length of time dur ing which the electrical action does continue.

its at present comstructed, the electrical action for the generation of ozone, can be varied from one and one. half seconds to two seconds, and thorn are two such closed cir cuits in a minute. A varying of the number of posts H" on the disk H will correspondingly vary the number of closed circuits in it given time. I have mentioned that the induction coil is )referohly supported in on inclosed rcce itocle.

I t is well known that on induction coil when in operation molccs much noise. I have dcviscd a. mode {or eliminating most of the noise it medics. This mode consists in suspmn'ling the coil so as to prevent the vibrations which occur in it from being conducted to the frame or other portion of the. machine that would respond to these vibrc-f tions somewrmt o soiuidingboard does in n musical instrument. My preferred means for so suponding this induction coil X are as .follows:-l locate the induction coil in a box X and suspend this box by means of a strap X which hitter goes down along-one side of ti l-z m and beneath tho box and u 1 alongside of the other side of the box. sch upper end X of this strap X is fastened to the iron c. To prevent tl'iis strap or bandage X from accidentally slipping sidewiscnnd ofl' irogu the box X, l iroride this box with 'cd c hinges X, our. ll angzc on catch verticn edge of this box X Bctwoon those flanges X the strap )1, and it is thus sccumly hold in place. As a. further guard for preventing any occidental! displacement of tho strap X, in roses where the top of thebox X does not come close to the support where the ends )1", X2 of the strap ore fastened, and when the box 3;, lifted, might allow the Oil strap X to so buckle as to let the box X out from the loop of it (the stra I rovidc two other straps X, X, secured at t ieir ends to those sides of the box X that are not occupied by the straps X 'lhese straps X respcctivcly cross over the stra )s X at their respective sides of the box k Thus the box X is not only suspended, but is securely held by its suspcnsory strap X Thus the disagrees hlc humming noise )roceeding from the induction coil is nearly a l prevented.

The machine as a generator of ozone for nervous ')O )[)l0 and for patients affected by such kinds of noise is rendered very acceptalilo.

What I claim as new, and of my invention and desire to secure by Letters Patent, is z- In a machine for the generation of ozone, the combination of the glass plates, induction coil batteries, circuit connections, and switch, and clockwork for interrupting and closing the circuit, and means for stopping the clockwork, substantially as and for the purposrs specified.
